2 Claims. 1.

The present invention relates to suction cleaners and more particularlyto cleaning tools for use with suction cleaners.

An object of the invention is to provide acleaning tool havingavalveactuated by relative movement between the wand and nozzle body tocontrol connection of the latter with the source of suction. Anotherobject of the invention is to provide. a cleaning tool having an airpassageway for directing a. high velocity air stream over the surfaceto: be cleaned. A further object. is. to provide. cleaning tool having.a. valve provided with a nozzle and also defining another nozzle. Otherobjects and advantages of the invention will be apparent from thefollowing description and drawings wherein:

Figure 1 is a sectional View of the invention illustrating the valve andits nozzle connected to a source of suction;

Figure 2 is a section partly in elevation showing the large nozzleconnected to the source of suction;

Figure 3 is a section taken along the line 3-3 of Figure 2; and

Figure 4 is a broken bottom view of the cleaning tool.

The embodiment of the invention herein disclosed comprises a cleaningtool 89 provided with an elongated nozzle 8! having its mouth 82communicating with a centrally disposed air passageway 83. Projectingrearwardly from the passageway 83 is a substantially Ushaped housing 85having a bottom wall 86 and opposed side walls 9l8l. Disposed in thehousing 85 is a conduit 38 having a rectangularly shaped exteriorsurface formed by opposed side walls 99-49, top wall 9I and bottom wall92. Rotatably mounted in each housing side wall 81 is a screw 93threaded into the adjacent side wall 99 of the conduit 88 to pivotallymount the latter on the cleaning tool body. The outlet of the airpassageway 93 communicates with the conduit 98 and the latter isconnected by a swivel joint 95 to a curved tube 96 adapted to beconnected to a suction cleaner in a well known manner. A resilient seal91 is provided between the Ushaped housing 85 and the adjacent walls ofthe conduit 88 to prevent passage of air therebetween.

A valve 99 is pivotally mounted in the nozzle mouth 82 by a pin I99projecting from each end lip Hit of the nozzle mouth into the valve. Thevalve 99 is actuated by a bifurcated member 98 attached to the lowerwall 92 of the conduit 88 and its recess I92 receives a lug I93projecting from the valve 99. When the tube 95 is raised or 2 loweredto. pivot the conduit 88: on the pins 93 with respect to the nozzle.body, then the member 98 pivots the valve 99 about thepins [99 to eitherof the positions. shown in Figures I or 2'.

Arranged within the valve 99, is. a nozzle: mouth I99 defined at itssurface contacting perimeter by a lip I99 having a portion serrated asindicated. at Hit, and the cross section of the nozzlemouth I95 is lessthan the nozzle mouth 92:. Que; longitudinal edge we of the valve 99cooperates with the end lips. Nil and front lip I98 to define thesurface contacting perimeter lip oi the large nozzle mouth 82 as shownin Figure 2. A suitable air seal is disposed between the edge I99 of thevalve 99 and the adjacent bottom wall of the housing 85.

In operation, when it is desired to remove nonembedded dirt from thesurface to be cleaned, the tube 96 is moved upwardly to position thevalve 99 as in Figure 2. If the cleaning tool is in the position shownin Figure 1 the tube 96 is rotated about pins 93 upwardly relative tothe nozzle body. Such rotation of the tube 96 moves the bifurcatedmember 98 counter-clockwise, as viewed in Figure 1, causing the valve 99to rotate clockwise about its pins I99 to the position shown in Figure2. In this position of the valve 99 the large nozzle mouth 82 is exposedto the rug, and the nozzle perimeter lip is defined by the front lipI98, end lips WI and the edge I09 of the valve 99. The large nozzlemouth 82 permits passage of a relatively low velocity air stream overthe rug to remove the loose dirt therefrom and thence through thepassageway 83, conduit 88, tubes 92 and 96 to the source of suction.

If the litter and dirt is embedded in the surface to be cleaned, thenthe valve 99 is moved to the position in Figure 1. In order to shift thevalve 99 to this position the tube 96 is moved downwardly about thepivot pins 93 relative tothe nozzle body causing the bifurcated member98 to move clockwise as viewed in Figure 2, to rotate the valve 99 aboutits pivot pins I to the position shown in Figure 1. When the valve is inthis position, its defining edges close the large nozzle mouth 92 andthe smaller nozzle I is in operative cleaning relation with the surfacebeing cleaned. The small nozzle mouth I05 causes passage of a highvelocity air stream over the surface being cleaned to remove clinginglitter and the air stream flows through the small nozzle mouth I95,passageway 83 and conduit 88 to the source of suction.

While I have shown and described but a single modification of myinvention, it is to be understood that this modification is to be takenas 3 illustrative only and not in a limiting sense. I do not wish to belimited to the particular structures shown and described, but to includeall equivalent variations thereof except as limited by the scope of theclaims.

I claim:

1. A surface cleaning tool comprising a body, means defining a firstelongated nozzle mouth in said body engageable with the surface to becleaned, a member substantially the area of said first nozzle mouth andmovable into and out of said first nozzle mouth, means defining a secondelongated nozzle mouth in said member and extending substantially thelength thereof and engageable with the surface to be cleaned, meansmounting said member on said body for movement of said member includingsaid second nozzle mouth into said first nozzle mouth in operativerelation with the surface to be cleaned, an air conduit pivotallymounted on said body for connecting said nozzle mouths to a source ofsuction, and means connecting said member and said conduit for relativemovement therebetween upon pivotal movement of said air conduit toeffect movement of said second nozzle mouth and member into the fullextent of said first nozzle mouth.

2. A surface cleaning tool comprising a body, means defining a firstnozzle mouth in said body engageable with the surface to be cleaned,valve means substantially the area of said first nozzle mouth andmovable into and out of said first nozzle mouth, means in said valvemeans defining a second nozzle mouth substantially the length of saidvalve means and engageable with the surface to be cleaned, an airconduit for connecting said first and second nozzles to a source ofsuction, means mounting said air conduit on said body for pivotalmovement to different positions, and means connecting said air conduitand said valve means for relative movement therebetween upon pivotalmovement of said air conduit to its difierent positions to move saidvalve means into said first nozzle mouth to cut off the major portion ofthe latter from the source of said suction and place said second nozzlemouth in operative relation with the surface being cleaned.
